T0 LZZ whom it" may concern:

Be it known that I, JOHN LANZ, a resident of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Swaging; and I do hereby declare thefollowing to be a full, clear, and eXact description thereof.

My invention relates to apparatus for forming car-axles and otherarticles.

Fig. 2i is a like view of a portion of the bar afterit haspassed Fig. 25 is a like view of the bar after it has been cut bythe shears, and Fig. 26 is a view of the finished axle.

Vhile I have illustrated and described my invention as applied to themanufacture of car-axles, yet l do not wish to limit myself in anymanner to that particular application of my invention.

YThe r'olls by means of which the ingot a is Fig.-

reduced to the barb of proper width andthickness may be of anywell-known form, and as they form no part of my invention I have onlyillustrated them in a general way in Fig. 1,

which is a diagrammatic view of the entire plant for carrying out myinvention..

The squeezer consists of the frame A,which is preferably located in apit A below the level of the workingiioor A2. Mounted in suitablebearings B' of the frame A is a shaft B, which is driven by a suitableengine B3. A spur-wheel $2 on the shaft B meshes with the gear-wheel Con the shaft G, mounted in suitable bearings C2. The opposite end of theshaft C has the elliptic gear-wheel C3, meshing with the like ellipticgear-wheel D on the shaft D', mounted in suitable bearings D2 in theframe. By the employment of the elliptic gears avariablc speed isimparted to the shaft D for the reason more fully hereina'fter setforth. The shaft D is an eccentrie-shaft and passes through the yoke E,which hasaslidingdovetailed connection with the slide-block El, as shownin Fig. 6. Links or toggles E2 connect the slide E with the `die-boxesF. These die-boxes are hinged together by means of the horizontal shaftF, which isY supported in bearings F"a in the frame. A cap F5 rests uponthe bearings F2, said cap being held in place by the'cap-bolts F6, whichpass up through the frame and have the nuts F7 screwed thereon. Thisholds the shaft F' down and prevents its rising when the eccentric-shaftcloses the dies. If, however, undue strain is brought to bear on saidshaft, the cap-bolts F6 will break or give iirst and relieve the strainon said shaft. The dies F3 are secured within seats F4 in the dieboXesin any suitable manner, said dies having their squeezing-faces of suchconfiguration as to give the desired swells or protuberances to therolled bar, as will more fully hereinafter appear.V This manner ofconnecting the eccentric-shaftD to the die-boxes F imparts motion toboth of said dieboXes,while the yoke E is permitted to move in ahorizontal and vertical plane simultaneously. This double movement isdue to the sliding connection with the slide E.

On one end of the eccentric-shaft D is mounted the crank G, which hasthe pitman G connected thereto. This pitman is con- IOO nected at itsupper end to the crank-arm H,- aslot Giin said pitman allowing for themove; ment of said pitman for a certain distance without engaging thearm H. The crankarm His connected to therock-shaft I, mounted inbearings I. Secured to the rock-shaft I is the inwardly-projecting armI2, which is adapted to engage a lug K on a verticallysliding gate K,working in suitable guides K2. At the lower end of the gate K isjournaled a roller K3. This gate K acts to close the pass between thefeed-rolls L L' until said rolls have revolved to a certain point, whensaid gate rises. The upper rollLis mounted in the housings L2. Thefeed-roll L is journaled insuitable brasses L3, adapted to move inguides L". A spring L5 is interposed be-v tween the brasses Ls and ablock L6. Setscrews L7 pass down through the top of hous ings andregulate the pressure on the springs L5. In this manner the upperfeed-roll L is permitted to yield in case too great a strain isbroughtupon it. The lower feed-roll L is Inonnted on the shaft M, journale'd insaid housings L2' and in the frame A. Gear-wheels L8' connect the rollsL L.

Between the dies F3 is the table or platform N, which supports theheated bar while it is being fed to said dies and discharged therefrom.ThisV platform or table N may be formed of a Tebar, and it rests withinthe forked end-s O of the curved arms O, which are pivoted at O2 to theframe. The table N has the slots N formed therein, with which j the pinswhich connect the arms O to said table en gage. This gives said table acertain amount of longitudinal play. The arm O i has; the adjustableweights Os on the ends thereof. The threaded bolts O'l act as stops toregulate the height of the forked ends O', and consequently the heightof the table N. By screwing down the nuts on said bolts O4 the weightsO3 act to elevate the inner curved ends of thelarms- O. Vhen sufficientdownward pressure is brought to bear upon the table N, said table willyield and the i nner ends of the arms O will descend,wl1ile the weightedends will rise for the purpose and in the manner' more fully hereinafterset forth.

on the Shaft M is me pinion M', which Ving press by which the blank isbrought to meshes with the large gear-wheel C. This pinion Ml is looselymounted on the shaft M and is held from sliding on the shaft M in onedirection by t-he collar M2, secured on said shaft, and in the otherdirection by the ange on said pinion overlapping the gear #wheel C. Theprojection Ml on the pinion M/ has the tapering seat formed therein. Aclutch P is adapted to slide on the shaft M, being splined thereto, saidclutch having the conical end PQ adapted to enter the tapering seat M5.The other end P2 of the clutch P is also tapering or coneshaped and isadapted to enter a correspondingly-shaped seat MG in the frame. Theclutch P has the annular groove P3, with l held Within the bed U'.

which the upper bifnrcated end R of the leverl R engages. This lever Ris pivoted to the bracket R2 on the frame. The lower knocker end R3 ofthe lever R engages the shaft C. The lever R has the weight R4. The camsS S on the shaft C alternately engage the lower end of said lever R atopposite sides thereof, whereby said lever is first moved to one sideand then to the other. In this manner the clutch P is also alternatelythrown into and out of engagement with clutch-face M5, whereby theintermittent rotary movement is imparted to the shaft M and rolls L L"for the purposemore fully hereinafter' set forth. -These cams S S/ areillustrated in detail in Figs. 7, 8, 9, and l0. The couplingbox S2 iskeyed to the shaft C. This box has the seat S3 with thelug S4 thereinformed integral with saidbox. The" ad jnstable cani S5 has a lug S6formed thereon,- which is adapted to ent-er the seat S3 and engage thelug S4 i-n said seat. A cam-'face S7 is formed on the adjustable camLiners SS may be interposed between the lugs Snl and S tor adjust thecam according to' the'inte'rvals of revoluthe insertion of -smallsheetiron liners where desired.

I will now describe the shears which may be used in connection with myimproved method o f forming axles. y

The reference-letter T represents the upper shear-knife, whichI hasl thedie or punch T for lindenting the upper face of thebar during theshearing of an axle length thereform. The lower shear-knifeU isstationary and is This lower shear knife U hasy also an indenting die orpunch U2, which is adapted to indent the lower face of the axle lengthjust cut. The knifeU has also thedie or punch U3, which extends abovethe bed U to form an indentation on the lower face of the bar, as willmore fully hereinafter appear. The shear-knife T has also a projectionT2, which forms a punch.

I will now describe the shaping or formguides extend through the bed andare con-v nected to a cross-head'll, which is forced downward by meansof the plunger l2, mov-V ing in the hydraulic cylinder 13, which isformed in and is a part of the bed 5. `The movable die 7 is raised bymeans of two smaller cylinders, one of which is shown in Fig. 13 anddesignated by the numeral llt.y The piston-rod l5, acting in thiscylinder,

IOO

IZO

lifts the cross-head 11 by means of the connecting-links 16, which areconnected to the shaft 17 at the end of the piston-rod l5. The dies 6and 7 are so arranged that two axles may be operated upon at the sametime with one stroke, the die-seat 18 acting upon one end and a portionof the length of the axle, while the die-seat 19 acts upon the oppositeend to complete the axle, said axle having been transferred to seat 19in the manner hereinafter set forth. The blank from which the axle isformed is run in upon the rollers 20, traveling in the direct-ion of thearrow, into the angular grooves 2l and is taken therefrom by means ofthe swinging arms 22, which will be more fully hereinafter described,and placed in the dies to be swaged or shaped. Two axle-blanks aropicked up at one time, each from opposite sides ot' the machine, bymeans of these arms 22 and are placed in the dies for the operation ofswaging. The operation of swaging then proceeds, the blank being turnedpartially during each stroke of the press until the blank is properlyshaped, when the die 7 is then raised and the arms 22 carry thepartially# forged axles across'from one die-seat to the other, where theswaging operation proceeds, finishing the other end of the axle andcompleting its formation. The finished axles are then carried, by meansof said arms 22, to the grooves 23 of the rollers 29, which have beenreversed, whereby thefinished axles are carried off onto suitableconveying apparatus and other blanks are fed into the rollers and theoperation is repeated.

I will now describe the arms 22 and the manner in which they areoperated.

The arms 22 are rigidly connected to the hollow shaft 24, which shaft issupported on rollers 25, which have their bearings in the hangers 26,said hangers being rigidly connected to the frame of tho machine. Asthere are two sets of arms 22 acting at the same time upon two differentaxles, I will describe one of them, as each set is alike and is operatedin the same manner. This hanger is pivotally connected in any suitablemanner at 27. The arms 22 are also supported at about their centers bythe hanger 28, which is secured to the end of the lever 29. This lever29 is fulcrumed at 30, the opposite end of this lever being connected tothe pistonrod 3l of the steam or hydraulic cylinders The hanger 28 isintermediately connected to the arm 22 by means of the clevis 33, and itis also connected to the lever 29 by meansof a clevis 34. These are forthe purpose of giving it universal movement. The hollow shaft 24 beforespoken of, to which the arms 22 are attached, is in two parts. One ofthese parts is enlarged near the center of the machine to form thehydraulic cylinder 35, the other part forminga piston-head 36,which issplined and operates within said cylinder 35. The

outer ends of these hollow shafts 24 are connecied by suitable hose orother flexible connections to a valve (not shown) through which theiiuid is admitted to operate said cylinder 35. At the outer end of thearms 22 is the bearing 37, in which is seated the shaft 38, the outerend of the said shaft having on its face the removable lugs 39, whichare designed to enter the depressions formed in the end of theaxle-blank,- as will more fully hereinafter appear.

IVhen it is desired to lift the blank from the rollers 2O to place it inthe dies, the arms 22 are swung backward by the operator, so that thelugs 39 come into alinement with the ndentations in the ends of saidaxle-blanks, and the arms are then drawn together by means of thehydraulic pressure in the cylinder 35, so that the lugs 39 enter saiddepressions in the ends of the axle-blanks, and the faces 40 of theshaft 38 grip the blank firmly between them. The cylinder 32 is thenoperated to lift the hanger 28 through the lever 29, and the axle-blankis thus lifted above the plane of the anvil 6 and is then swung in overone of the die-seats by hand or any suitable power, and pressure is thenreleased in cylinder 32, and the blank is allowed to drop into thedie-seat. As before described, a blank is placed in the other die-seatfrom the rolls on the opposite side of the anvil.

In the operation of forging the axle it is necessary, as before stated,to turn the blank after each stroke or succession of strokes, and toaccomplish this the shaft 38 is mounted in its bearing 37 by means ofthe antifriction rollers or balls 4l. The shaft 38 is enlarged at itsouter end, forming a shoulder 43,. This shoulder acts as a cone, whichbears against the balls 4l and is held in place by means of the jam-nuts42. The handle-bar 44 has a square eye in the center thereof, adapted toengage with the square end of this shaft and is grasped by the operatorwhen he desires to turn the blank. As there are two of these arms usedin picking up the axle-blank and as it requires but one operator foreach blank, it is necessary to have the lugs 39 at the opposite end ofthe machine from the operator come into proper alinement with theindentations on the axle-blank automatically. To accomplish this, theouter end of the shaft 38 has a flattened lug 45, against which a spring46 operates, so that this shaftlwill be automaticall y turned intoproper position for clutching another blank whenever it is free tomove-that is, immediately the completed axle has been dropped.

Vhen the axle-blank is run in upon the rollers 20, it is necessary toprovide a stop to keep it from going too far. To provide for this, aweighted arm 47 is pivoted to the anvil 6 at 48. This arm is forced downout of the way by contacting with the outer end of the shaft 38 when itcomes into position to drop the finished axle. When a new blank has beenreceived by the carrier device and has been lifted to the dies, this armis raised into proper position by means of the Weight 49, so

IOO

that a blank coming in upon the rollers 2O will not g'o beyond theproper position. In linewith the rollers 2O are the tilting rollers 50,one of which is represented in Fig. 12. These rollers 50 are journaledin the forked ends 5l of the forks 52, which are adapted to swing on theshaft 53. The tilting rollers 50 are arranged in such relation to theendless carrier 54 as to receive therefroml the axleeblanks` conveyed bysaid carrier. This carrier 54 has the lugs 55 at intervals there on,which'l engage with the axle-blanks and carry said blanks and deliverthem onto the rollers 50.l In order to receivethe axleeblanks from thecarrier 54, the forks are moved t0 the positions shown in Fig. 12',whereupon the axle-blank `is deposited within the angular grooves 56 insaid rollers, which are in line 'withl angular grooves 21 of the'rollersQO'. The

finished axles as they are carried off in the grooves 23 of the rollers20 pass into the curved grooves 57 of the rollers 50, whereupon saidrollers are tilted into the opposite position from that s'ho'wn in Fig.12, and the forged a-X'lesare deposited on the carrier 54- to beconveyed to the finishing department. y

The operation of the mechanism is as fol# lows;` A suitable ingot Ct,such as illustrated in Fig. 2l,- having been properly heated is passedback and forth through the rolls c while supported on thefeeding-tablefd- The ingot is passed from one side of the rolls totheother through Asuitable passes until it has been rolled out tothe fulleXtentin said rolls. The bar when thus rolled is transferred onto theapron f, parallel with the apron d. The apron f travels on the rails c,and said apron is brought into posi-'tion tov continue the rolling ofthe bar through several passes of the rolls c until a bar b has beenrolled from the ingot d of suitable width and thickness. The apron g,traveling on the tracks h, acts in conjunction With the apron fduringthis rolling` through the rolls c'. The apron f has the hinged sectionf, which -is shown elevated in Fig'.V 2. It is drawn up by means of thechain f2, working over pulleys f3 on standard f4. This hinged sectionwhen drawn up reduces the length of the apron, so that the same apronmay be used for the rolls c', as well as the sque'ezer. The bar o whenproperly reduced is transferred to the apron f. It will then be fedforward by said apron until its front end comes against the roller K8 ofthe gate K. The squeezerhaving been put into operation and the partshaving been set at proper positions with reference to each other toprovide for the squeezing of the bar at proper intervals, the pitman G/will raise the crankarm I-I, so' as to move the rock-shaft I. Thismovement of the rock-shaft I will raise the ari-n I2, and consequentlythe gate K. Upon the withdrawal of the gate K the bar o will be fed inby the rolls L L onto the table N between the squeezing-dies F5. The barZ2 is carried in between the dies F3 by the rolls L L', the roller K3rolling on said bar far enough to make a short' crop end and giveastart-l ing-'point on' the bar for the next revolution ofthe squeez'er.When the bar b has been fedl into the dies the proper distance, thefeed-A rollers L L are stopped. This stoppage of the feed-rollers" Ll Lis 'caused by the cain S moving around in such position as to' throw thelever R into such position as to bring the conical end P2 intoengagement with the seat M6r in' the frame and withdraw the conical endP from the seat M5 in the pinion M. The friction of the conical end I32in the seat M6 of the rigid frame will tend to stop the rotation of therolls and the momentum of the bar, and the pinion h being looselymounted on the shaft M no further rotary movement is imparted to saidshaft M, and the bart) comes' to a standstill. y rolls are stopped theeccentric'shaftD will Immediately the feedhave come into such positionas to advance the die-boxes Ftoward each other, as represented in Fig.6. This movement of the ec" centric-shaft D' is caused by the ellipticgearwheels 03D, mounted von the shafts C and D', respectively. Theconnection of the ec# centric-shaft to the die-boxes in this mannergives motion to both dieboXes`and the yoke moves horizontally andvertically simultane ously, the said oontr'am'ovement being com-lpensated for by the slides. The elliptical gear-wheels give theeccentric-shaft the variL able speed upon each revolution, which is es`sential to give more time to feed thebar to the dies and less time ofcontact ofthe dies on the bar, thus reducing the loss of heat in thebar. The bar b' therefore' having been fed to the dies F3 and ,said`dies having been advanced toward each other in the manner describedportions of the 'section of the bar v comprised within the length of thedies are subjected to the squeezing action of the same. The dies F3 inthe making of an axle are given a coniigu'ration such as vwill give theform to' the bar represented in Fig. 2 squeezed edgewise and conforms tothe con'- iiguration'of said dies, whereby said bar is f changed` toirregular rectangular form, but, not materially changed as regards itsarea in l cross-section. dies, wlill in plan View be contracted at itscen- Th'e barb is The section t', squeezed by the tral ortion, as at t"and will o'rad ually increase p a a in thickness to the extentrepresented at t2,

while beyond i2 will be the inwardly-'tapering ends 3. A side view ofsaid blank is represented in the same Fig. 23, showing that by thecompressing of the central portion z" edgewise a corresponding swell t4has been given to the upper and lower faces of the blank and by theformation of the inwardly-tapering end '3 a swell or protuberance Vhasbeen formed on said faces of the blank., As the squeezing operationtakes place it is apparent that the swells formed on the upper and lowerfaces Y ofthe blank resting upon the platform N will cause said platformto yield, for which provi-v sion was made in the manner hereinbefore setforth. When the' dies F3 have squeezed the IIC bar and have formed thesection thereon reprew sented by the letter t', Fig. 23, the eccentricshaft D' will revolve further and withdraw the die-boxes F, releasingthe dies F3 from contact with the blank. At the same time when thedie-boxes F have withdrawn enough for clearance of projections of thedies the cam S will have come around in such position as to throw thelever R over to bring the conical face P into the seat M5 in thegear-Wheel M. This will cause a further rotation of the feedrolls L L',whereupon the bar b will be fed by the feed-rolls into position upon theplat form N, so that when the eccentricshaft D comes around anotherblank-section t' will be squeezed in the manner hereinbefore set forth,the feed-rolls L L having been stopped as before. In this manner the barh is squeezed into a multiple of blank-sections suitable for formingaxles. After the bar has been passed through the squeezers it will restupon the apron g. It is then transferred by the apron g over the tracks7i into line with the end passes of the rolls c. The apron f is alsotransferred by the tracks e `to the rolls c, and the bar l? having beensqueezed in the manner described is passed through the rolls severaltimes until the swells or protuberances i4 t5 arereduced and the barfurther elongated, so that it is brought to the forms represented inFig. 24, in which the first form is a plan view and the second a sideview, showing that the swells or protuberaneeshave been reduced andelongated, leaving the bar with flat and even upper and lower faces. Theblank-sections in crosssection will have such areas as will correspondsubstantially to the areas in cross-section of the finished axle takenat the same points. In this manner the metal is properly distribut-edfor the shaping process. The bar having been rolled out with flat andeven upper and lower faces, as in Fig. 24, it is carried onto thefeed-table j in position to be fed to the shears 7.a. As Fig. llillustrates these shears in detail, I will describe the operation ofshearing with reference to that figure. The bar traveling in thedirection of the arrow is carried under the upper shear-knife, restingupon the lower bed UC The cropend formed in the squeezers is firstsheared from the bar, and when this crop end is sheared off the upperknife T in shearing this crop end descends far enough to force the dieor punch T into the upper face of the end of the bar, while the punch U3on the lower knife is forced into the lower face of the bar to form anindentation therein. This is caused by the force of the descent of theupper die with the bar resting upon the punch U3; In this manner incutting off the crop end indentations t, such as are represented in Fig.25, are formed at the end of said bar upon its upper and lower faces.The

crop end having been sheared off and the indentations formed asdescribed, the bar is then fed into the shears the length of theblank-section, whereupon said upper knife T again descends and in itsdescent the blank sheared off is forced by said upper knife T down ontothe punch U2. The pressure of the upper knife forces the punch U'fa intothe axle-blank to form an indentation on its lower face, while theprojection T2 of the knife T forms an indentation on the upper face. Inthis manner the axle-blank is provided at each end with the indentationst6. In cutting off this blank from the bar like indentations are formedin the manner here inbefore described on the end of the bar which is toform the next axle-blank. As the axle-blanks are cut from the bar theydrop onto the rollers m. The carrier n, similar to the carrierrepresented in Fig. l2 and having lugs thereon, carries the axle-blankover to the feeding-rollers o at the mouth of the con tinuous f u rnacep. The axle-blank is fed into the furnacep, and its heat is retained orproperly raised, when it is carried by the rollers in said furnace outonto the rollers q. W'hile the furnace may contain a number ofaxle-blanks, onlj7 two are carried therefrom at one time to betransferred to the hydraulic press. from the rollers q and carries theminto the angular grooves 5G of the rollers 50, as represented in Fig.l2. The forks carrying the rollers 50 are swung into such position thatthe axle-blank will enter the grooves 56 of the rollers 5.0, and asthere are two sets of these rollers 50, as represented in thediagrammatic view, Fig. l, the rst set will have to be tilted out of theway to allow the axle'- blank to pass over it to the second set. Whenone of the axle-blanks has passed over the first set of rollers 50 andhas been deposited The carrier 54 takes the axle-.blanks IOO in theangular groove of the second set, the f other axle coming along on thecarrier 54 is received by the iirst set of rollers 50. The forks of therollers are then brought to a vertical position, whereupon theaxle-blanks will be in line with the angular grooves 21 of the rollers20, resting in the angular grooves 2l of the same. l The axle-blanks arecarried on said rollers until their forward ends strike the stops 47.The swinging arms 22 are then swung back in position to vbring theshafts 38 in alinement with the axle-blanks, so that the lugs 39 on theends of said shafts can enter the indentations 116, formed in the endsof the axle-blanks. The lowering of the arms 22 to effect this resultwill force the stops 47 out of the way in order to permit the lugs 39 onthe ends of the `shafts 38 adjacent thereto to engage withtheindentations on the inner ends of said blanks. This movement of thearms is effected by suitable levers which operate the pistons in thecylinders 32. The lugs 39 on the shafts 38 having been brought intocoincidence with t-he indenta'I tions of the axle-blanks, the front andrear shafts 3S of the arms 22 are then moved toward each other7 so as tobring the lugs 39 into engagement with said indentations This isaccomplished by admitting water or steam to the cylinder 35, whereuponthe hollow shaft 24.,- recedes within said cylinder 35 far enoughtoforce thelugs39into theindentations in the ends of the axle-blank andhold the .same securely therein. The axle-blanks having been grasped inthis manner by the arms 22, said arms are then swung over in suchposition as to lower the axle-blanks into the die-seats 18 and 19, saidblanks being placed in said grooves edgewise. The movable die7 is thenlowered and the greater part of the-axle-blank in the die-scat 18 isacted on so as to shape said part of the axle-blank so acted on by thedies to finished shape,while the die=seat 19 acts upon the greaterv partof the other axle-blank in the same manner. While the axle-blanks' arein the dies, said blanks are turned by means of the handlesbar 44, whichhas its eye engaging the end of the shaft 38. By turning this handle-barthe axle is turned into d'ifferentpositions in order to be properlyshaped. Accordingly I have two axle-blanks shaped for the greater partof their length to the desired shape of the finished axle; but it is'necessary now to give the entire axle, the finished shape, which is donein the following manner: After the axle-blanks have been shaped for thegreater part of their length the blank in the die-seat 18 is transferredto the die-'Seat 19 and the axlesblank in the dieseat 19 to the die-seat18. This is accomplished by swinging the arms 22 into suclr positions asto effect this result, whereupon the forging operation is again repeateduntil theends of the axle-blanks not finished by the' first forgingoperation are brought to the The axle will then be in the forni shown inFig. 2G. The finished axles are lifted from the die-seats while stillheld by' the arms 22 and are transferred to the grooves 23 of therollers 20. When deposited on said rollers, the piston 36 in thecylinder 35 is operated to release the shaft 38y of the arm-s 22 fromengagement with the finishedaxles. Power is applied to drive the rollers270 in theA proper direction, when the axles resting thereon will becarried into the grooves 57 of the rollers 50. By tilting said rollers50 in thel manner hereinbefore set forth the fin'- ished axles aredumped onto the carrier 54 and transferred thereby to a point Where theymaybe loaded on cars for transportation.
